Makita 18v angle grinder red lights flashing wont start. Had new brushes & controller

SOURCE: makita dc1804f charger will not charge new i-mh 1834 18v battery

I think your tryiong to charge NIMH batteries oon a charger designed for Lithium Ion batteries. With all the new style batteries such as NICAD, NIMH and LI-ION, charging becomes difficult. Most chargers pre NIMH and LI-ion, were designed for NICAD's. The best advise, match your batteries with the correct charger

Hi, Don't stress, its working fine. The grinder has a sort of self test when you put the battery in, it blinks. What you don't want is the light to come on when you are using it. That means that you are bogging it down and if on for 30 seconds ( if I remember right) it will shut the grinder off until you reset it by turning it off and then on again. So no worries!

Take apart the rear portion of the case -- the part the cord enters -- two halves -- screws in side -- you'll see the brushes -- they are in holders held in by springs and plug into the winding.

check inside for any loose connections plus check the brushes. if like you say it is smoking it could be a trip to the wheelie bin for that one.

SOURCE: angle grinder eats carbon brushes

Yes, the rock dust is what's destroying your brushes and armatures. It gets sucked into the rear vent slots and gets to those parts and eats them away quickly. I don't know of any vacuum systems make by Makita but there are some companies that make them for their systems. Blastrac is one that comes to mind but they can be real expensive systems. I don't know of any grinders with sealed brush/armature systems, they have too much heat to disipate. To make your Makita grinders last longer make sure you are cutting with the side of the blade that directs the dust away from the case and try to have a strong airflow blowing the dust away from the grinder to minimize the dust taken in at the back of the grinder.
